PSS Filter Elements

Summary

Product identification

PSS® Series filter elements are composed of 316 low-carbon stainless steel powder sintered together in an inert environment. The medium provides a fixed pore structure, quantitative particle removal efficiency without media migration or particle unloading, inherently high void volume, low resistance to flow, and high dirt holding capacity. These filters are repeatedly cleanable and offer broad temperature and chemical compatibility.

They exhibit high chemical stability and do not impart taste, odor, or extractables to the effluent.

Applications

• Chemical process industry
• Aggressive environments requiring critical filtration levels
• Industrial gases (cryogenic and high temperature)
• Steam
• Solvent
• Heat transfer fluids
• Polymers
• Chemical intermediates
• Food and beverages

Operating limits

• Collapse differential pressure (Standard 316 stainless steel cartridges):
  • 50 psid in the forward flow (outside-in) direction up to 600°F (✝)
  • 50 psid in the reverse flow direction
  • ✝Threaded connector series only. 1000 Series suitable for applications up to 450°F due to seal limitations.
• Temperature: Designs available for temperatures up to 1250°F with appropriate alloy selection.

Physical characteristics

PSS filters are available in three styles:

• Industrial (1000 style): 2 3⁄8-inch diameter double open-ended modules in incremental lengths of 10 inches.
• Sanitary design (AB style): Closed on one end with an O-ring piston seal on the other end.
• Cylindrical elements: 1 1⁄2-inches or 2 3⁄8-inches in diameter, closed on one end with a threaded fitting connection on the other.

Notes on performance data

• Removal ratings with * (e.g., 50%) should be used when comparing PSS to competitive grades.
• (1) Liquid removal efficiency ratings are based on a modified F2 test method and actual particle count data.
• (2) Weight percent removal data based on AC Fine Test Dust in air. Absolute retention ratings based on actual particle count.
• (3) Pressure drop in psi obtained by multiplying value shown by actual flow desired in gpm, viscosity of liquid in centipoise (if other than 1 cp), all divided by total filtration area (ft²).
• (4) Pressure drop in psi obtained by multiplying value shown by actual gaseous flow rate desired (acfm), ratio of viscosities (Actual viscosity of gas in cp / 0.018 (viscosity of air)), all divided by total filtration area (ft²).
